Aircraft involved

Probable cause & findings

The pilot's failure to maintain lateral control and to attain adequate altitude during takeoff with a quartering tailwind in gusting wind conditions, which resulted in impact with a sandy berm left of the runway.

Factual narrative

The sport pilot reported that during takeoff with a quartering tailwind of 10 knots, gusting up to 20 knots, as soon as the wheels left the pavement, the tail was pushed to the left. He straightened the tail and maintained wings level; however, the airplane was drifting to the left. The pilot reported that due to the tailwind and high altitude, he was getting very little lift. The airplane subsequently contacted sandy terrain on the left side of the runway. The airplane sustained substantial damage to the right wing and fuselage. The pilot reported that there were no mechanical failures or malfunctions with the airplane that would have precluded normal operation.

The pilot reported that, due to the tailwind and high altitude, the airplane was getting very little lift. The airplane subsequently impacted a sandy berm off the left side of the runway. The airplane sustained substantial damage to the right wing and fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.        Source: NTSB Aviation Accident Database Retrieved: 2026-02-12
